You just made a human life with this person. You got an engagement ring to celebrate your bond, a wedding band to symbolize eternity together and you should have a really precious piece to symbolize the birth of your child. This practice is 1000 years old. Men gave women gifts to appease the goddess Juno Lucina, who protected women in childbirth. DH gave me a pendant shaped like her http://www.jlucina.com. It was the cost of a really nice dinner and a night at the theater, most of which I truthfully can't recall every detail of. But this I will have my whole life to remember each time I look at it, and it will be passed down to future generations, forever.
